SPECIFICATION forming part of Letters Patent No. 445,714, dated February 3, 1891.

Application filed September l0, 1890. 'Serial No. 364,583. (No model.)

l To til whom it may concern.-

Be it known that I, PAUL DICKINSON, a citi- Zen of the United States, residing at Chicago, in the county of Cook and Slate of Illinois, have invented a new and useful Improvement 4in Chimneys, of which the following is a speciiication.

My invention relates to an improvement in the class of chimneys adapted for use in ventilating, and more especially as a smoke-stack in the roof of a railway-station shed as a fine for the escape of smoke from the locomotive sta-ck.

More particularly stated my invention relates to an improvement in the construction of a chimney of the class referred to, which is formed with cylindrical sections placed to extend partly above and partly below the roof, and having the last-named portion pivotallysupported to yield to and thus be uninjured by concussion against it of a locomotive, the lowest section being telescopically adjusted in position and counterbalanced to permit of its ready adjustment with relation to a locomotive smoke-stack. Such a chimney 1s commonly surlnounted by a cap forming a cowl or ventilator.

The objects of my improvement, which involves the general construction thus outlined,

.are to provide a construction of the pivotal a view in elevation of myimproved chimney;

Fig. 2, a vertical longitudinal section of the same represented as being supported. o n a roof, shown broken and in section; Fig. 3, a broken sectional view in elevation, enlarged, and showing the means for pivotally supporting the lower section of the chimney; Fig. 4,

A is the chimney formed V4in longitudinal sections r and r', preferably of cast-iron, the lower of the two sections r being flanged, as shown at no, to enlarge its upper end and thereby form a seat for the lower end of the section above it. Of course if there be more than two of the sections o, they may be similarly tted together. That part of the chimney which hangs below the roof B, I support thereon through the medium of a collar q, having a lateral flange q' extending around its base and resting on suitable props p, arranged to sustain the collar in a horizontal position on the roof. The parts shouldbe reenforced by means of a suitableangle-brace 0, as shown. A collar n, having a flange n', is inserted into the lower end of the lower section r, and the sections r, forming the portion of the chimney under the roof, are rigidly secured together in their suspended relation by means of tie-rods m, extended through the flanges q and n of the collars q and it and fastened with nuts m.

The section r is seated on the flange q around the collar q, and is rigidly fastened in' place, guy-rodsZ (indicated in Fig. 2) affording desirable means forthe purpose. The uppermost section o" is surmounted by a Ventilatingcap C, formed of a hollow conicaldeilector 7c, secured to an inverted hollow cone-shaped or substantially cone-shaped top 7a', fastened to the section just below its upper end. On the cone 7o is supported, through the medium of suitable legs i, fastening the parts together, a deflector in theform of a conical frusturn 7a2, surmountcd by a hood 7g?, supported and fast ened in place by means of suitable legs t. Between tho parts 7a2 and 7.;3 are two overlapn ping dcflcctors in thc form ol hollow conical frustums 7n and 7.15, the former being secured to the legs t" and the latter to the upper end of the defiector 7a2, between which and the deflector c there is thus no open passage. The lower collar it forms the support for the lowermost section r2 of the chimney, which section is pivotally fastened in place. From opposite sides of the upper end of the section r2 extend perforated lugs 7L,each of which is extended between a pair of similar lugs g, depending from the base of the collar-flange n at opposite sides of the center, andthe pivotal connection is afforded by bolts g or pins IOO passed through the lugs 7i and g. On the horizontal flan ge n. I provide a vertical ange f, extending downward therefrom to envelop the upper end ot the pivotal section fr?.

The drop-section r3, which fits, as usual, telescopically the lowermost section of the chimney, is provided with the ordinary hood e, and supported in a manner to adapt it to be readily adjusted vertically. For this purpose I employ bails d, fasten ed' at their forked extremities to the upper side of the hood e at opposite sides of the section r, wherebya `stable suspending means is afforded, and fasten to them the cables d', which are passed over pulleys o, suspended on hangers c', depending from the collarflange Q', and the cables are weighted at their hanging ends, as indicated at tu in Fig. 2, to counterbalance the drop-section in any position to which it is adjusted, the movement thereof to adjust it being readily effected by raising or lowering the weight in.

From the foregoing` description it will be apparent that my improved construction affords a durable chimneyA, since the part underneath the roof B, which is pivotally movable, is comparatively light, and thus does not bear so heavily on its pivot as to tend to cut or wear the latter, and the accidental running against it of a locomotive is not liable to demolish it, though if it should, being only a single section, it may be readily replaced by a new one with comparatively little expense. The construction of the cap C is also particularly effective as a ventilator, since it affords three oblique passages for the entrance of aircurrents in an upward direction to effect the desired draft th rough the chimney and a transverse draft-opening at its extreme upper end just below the hood 7c3. Besides, the details involved in the construction of the sectional chimney render it comparatively cheap and easy to manufacture, put together, and take apart.

What I claim as new, and desire toV secure by Letters Patent, is

1. In combination with a roof, a chimney A, formed in connected sections and extending partly above and partly below the roof, the lower portion being` pivotally suspended from a pivot below the roof, substantially as described.

2. A chimney A, formed with connected sections 1' and r', to extend, respectively, below and above a roof B, and a section r2,piv otally suspended yfrom a pivot below the roof in engagement with the lowermost section r, substantially as and for the purpose set forth.

3. A chimney A, formed with connected sections and r', to extend, respectively, below and above a roof B, a section fr?, pivotally suspended on the lowermost section r, and a dropsection r3, having hails d secured to its hood e, and suspended and counterbalanced t rom the said bails, substantially as described. 4. .A chimney A, formed with sections r and fr', to extend, respectively, below and above a roof B, a flanged collar q for supporting the portion extending above the roof, a flanged collar n for sustaining the portion below the roof, and tie-rods m, connecting the said collars from their flanges and holding the sections r together, substantially as described.

5. In a chimney A, the sections r r', fastened together, a section fr?, pivotally supported on the lower section r, a drop-section r3, suspended to telescope with the section r2 and counterbalanced, and a ventilator C on the upper end of the chimney, formed with the conical deflectors k 7a2 and hood k3, and the conical deflectors 7c* and 7,@5 between the hood and deflector 7a2, substantially as described,

6. A chimney A, formed with connected sections r and 7"', to extend, respectively, below and above a roof B,1langed collars q and n, connected by tie-rods m and clamping the sections fr between them, lugs f, depending from the vcollar n, and a section r2, having a drop-section r3, supported to telescope with it and provided with lugs 7L at. its upper endpivoted to the lugs g, substantially as described.

7. A chimney comprising, in combination, sections r and fr', to extend, respectively, above and below a roof B,a flanged collar q, affording a seat for the part 0"', a ventilator C on the upper end of the chimney, formed with conical defiectors k 7a2 and hood 7c3, and the conical detlectors 7a4 and fc5 between the hood and deflector 7a2, a collar n, provided with a horizontal flange n anda perpendicularlange f, and sustaining the sections r, tie-rods m, fastening the collars together at their horizontal flanges and clamping the sections r together, lugs g on the collar n, a sect-ion r2,having at its upper end lugs h, pivoted to the lugs g on the collar n, a drop-section r3, telescoping with the section r2 and having bails d secured toits hood e, and cables d', fastened to the bails,passing thence over pulleys c, and provided at their hanging ends with counterbalancing-weigh'ts w, the whole being constructed and arranged to opera-te substantially as described.
